The banner above has been tweeted and retweeted by a number of jihadists. It shows several photos of Abu Khalid al Suri, Ayman al Zawahiri’s main representative inside Syria until he was killed in a suicide bombing on Feb. 23.

Abu Sulayman al Muhajir, a sharia official in the Al Nusrah Front (al Qaeda’s official branch in Syria) who formerly preached in Australia, retweeted it earlier today. The English accompanying the banner reads, “We will never forget Sheikh Abu Khalid May Allah curse his killers and those who ordered it.”

Of course, Abu Khalid’s killers were most likely sent by the Islamic State of Iraq and the Sham (ISIS), the former al Qaeda affiliate that is fighting with Al Nusrah.
